Learning Goal: I’m working on a programming exercise and need an explanation and answer to help me learn.
Course name : ENTD261
Week 4: Node.js
Instructions
Create a simple Node.js server (Save as w4_fougnigue_soro.js) . Create a restful application similar to the one in lesson 4 (ReSTFul Web Services). Document the routing table, and the application you created.
Submit your week 4 work in w4_fougnigue_soro.txt (Please save the file as a text file and upload the text file here for final review.)
Note: node MUST be installed in the entd261 folder. Your code must be saved to the entd261 folder. node cannot be installed in any other folder. Be sure you have done this, or the code will not run in the command line.
Please refer to the attached sample solution file, w4_first_lastName.txt, for help. In place of first and lastName in the file name make sure your first and last names are present.
